🤓 Based on our data, we think this question is relevant for Professor Buckholz's class at UNM.

Solution: In sexually reproducing organisms, meiosis generates haploid (1n) gamete cells  from diploid (2n) cells. The n represents the number of chromosomes in a cell's set of chromosomes. Haploid cells have one set of chromosomes, where diploid cells have two sets of chromosomes.How does a zygote form from gametes?A. Two haploid gametes combine to produce a diploid zygote that can develop into an embryo.B. Each haploid gamete replicates its set of chromosomes to produce a diploid zygote.C. A haploid zygote forms from the gamete with the strongest alleles and the other gametes die.D. The four gametes fuse into a zygote with a twice as many sets of chromosomes as a diploid cell.

Problem

In sexually reproducing organisms, meiosis generates haploid (1n) gamete cells  from diploid (2n) cells. The n represents the number of chromosomes in a cell's set of chromosomes. Haploid cells have one set of chromosomes, where diploid cells have two sets of chromosomes.

How does a zygote form from gametes?

A. Two haploid gametes combine to produce a diploid zygote that can develop into an embryo.

B. Each haploid gamete replicates its set of chromosomes to produce a diploid zygote.

C. A haploid zygote forms from the gamete with the strongest alleles and the other gametes die.

D. The four gametes fuse into a zygote with a twice as many sets of chromosomes as a diploid cell.

Solution

Meiosis is known to be a type of cell division that produces haploid cells from the diploid parents. This process would lead to the creation of a diploid zygote from the haploid parents. But it should also be remembered that the haploid cells are from the same type of organism. That simply means that the source of the genetic material is still a diploid.
